Research on the Formation Stages of Oil-gas Reservoirs in Beier Depression of Hailaer Basin
摘要
Abstract
On the basis of illite dating method, hydrocarbon generated and hydrocarbon expulsed process and homogenization temperatures of fluid inclusion, formation stages of oil-gas reservoirs in Beier depression of Hailaer basin are studied. It shows that there are two main formation stages of oil-gas reservoirs in Beier depression of Hailaer basin. The first stage is about 120 - 80 Ma, which is corresponding to sedimentary period of Yimin Formation-early sedimentary period of Qingyuangang Formation, which is the main formation time of oilgas reservoirs in Beier depression of Hailaer basin. The great majority of formation period of oil and gas is 105 -90 Ma, which is corresponding to second-third segment sedimentary period of Yimin Formation. It is the abundant period of hydrocarbon generated and expulsed process , and sufficient migration force is helpful to formation of oil and gas reservoirs. The second stage is from Qinyuangang Formation to now which is second formaiion process of oil-gas reservoirs. The oil-gas reservoirs formed in the first stage is adjusted in the second stage.关键词
